Per statistics for the week ending this past Sunday, only one summons was issued in the 84th precinct, covering Northwestern Brooklyn. None were issued in the 79th precinct, covering Northern Brooklyn.

In the week prior, the two precincts had issued 626 parking, moving and criminal summonses.

Officers Weijian Liu and Rafael Ramos operated from the 84th precinct, but were working in the 79th December 20th, when 28-year-old Ismaaiyal Brinsley shot them execution style in their patrol car.

Their murders touched off a firestorm of rage within the NYPD. At a press conference New York City Mayor Bill de Blasio held shortly after the shooting, many officers turned their backs to him. Many did so again when de Blasio spoke at Ramos’ funeral Saturday.

Patrolman’s Benevolent Association President Patrick Lynch, along with former Mayor Rudy Giuliani, have publicly blamed the mayor for the killings, claiming he didn’t do enough to crack down on people protesting the Michael Brown and Eric Garner cases.

The summonses slowdown appears to be the department’s latest reaction. “Guys are on edge,” one anonymous police supervisor told the News. “They’re still angry at the mayor and they’re not about to do anything they don’t absolutely have to do.”

It also seems to be spreading beyond Brooklyn. Throughout the city, only 2,128 summonses were issued this past week, a sharp drop from 26,512 the week before that. Drug arrests for this past week are also down-115 from 523; officers notched only 14 gun arrests, compared to 35.

Even transit arrests have plummeted since the shootings. Officers made a miniscule 20 arrests, down from 662; housing arrests have dropped to 65 from 258.

The NYPD has refused repeated NYDN requests for comments on the numbers.
